Thisingvention'-relates to wind and tide motors. f f j t is an object of the invention to provide a motor whichA may be driven by wind or tide (or by any moving current of air or water, whether naturalor artificial) which will be fully responsive to fluid currents moving transversely to the shaft of saidv tion attains by the construction hereinafter described and illustrated inthe accompany ing drawingY wherein:

Figure 1 is a view'in the improved motor. Y

Figure 2 is a horizontal sectional view of the .sa-me taken upon the line 2-52 of Figthe side elevation of f ure 1.

Figure 8 is a view'in side elevation showing the mounting of the improved motor upon a tower. Y

In these views the reference character 1 designates a shaft which as disclosed is vertically mounted and which carries a plurality of vanes 2. Said vanes may extend substantially vertically at their edges engaging the shaft 1 but may be-formed of any suite.

able sheet. material and are each preferably reinforced by a framework comprising upper and lower rods 3 and 4, radially cai'- ried by the shaft 1, and a substantially spiral rod 5 rigidly connecting the outer ends of the rods 3 and 4.

The shaft 1 is journaled above and below the vanes 2 in bearings 6 respectively cari'ied by a sheet metal disk 7 and a spider member 7a.

The said disk and 1 spider member areI mounted fast upon a fluid guide which comprises top and bottom spaced plates 8 and verticalV deflectoi members 10 rigidly connecting the members 8 and 9, between the latter. The plates 10 are all tangential to a circle of somewhat lesser radius than that of any direction and encountering the motor will be and9.

effected by; said' aga' piftoiis'of sad venes. Preferatly'the disk 7 vandbottoin spider'a'are carried by collars` 60 11 Vwhich project rigidly upwardly' and downwardly from the plates 8 and 9.

adatti "stili/echter `When utilizing wind j energy it is'preferred to mountthe described motor, as is;

best seen in Figure 3, upon a suitable tower 12, as for example, that shown in Figure, since as a.V rule, a stronger air current will be encountered at some elevation above the'v ground. The shaft 1` of the motor mayeX-` tend down through the tower and may beV geared` as indicated at 13'to drive a generator 14 or todeliver motive power wherever desired. f If the deviceV is to be energized by tides, it is immersed as best shown in Figurel.

`VVlietlier the described motor is energized tage that any current moving ciencyupon the rotor. rlhis follows from the fact thatthe. members 10 act both to deflect the current against the outer portion .745 by air or yby water, it possesses the advanl A y horizontally (or substantially'jso) acts with equal effi-y of the va-nes, at one side ofthe shaft, and. also to shield the vanes at the kother side of the shaft from any im-pulsefrom said current. Thus, regardless of the current direcl tion. (so long assucli direction is substan-` tially horizontallthe current is equally ef.-

fective to drive the described motor.

The ability of the described'motor to respond rotatively in a constant direction to vforces acting in various ldirections Vand even to forces acting oppositely makes the described motor particularly capable of utilizing ythe tide energy since rthedirection of driveis unaltered *byV reversal of the'tide, and both the surface current and the reversely flowing underlying Vcurrentare utilized, when an under-tow prevails.

It is to be noted that the described con-V struction is well adapted to be built inlarge units, yielding a high'output of power, since the construction is not required to swivel for u the purpose of conforming to current variations, as is true of constructions heretofore used.

It is evident that the direction of drive of the motor will be reversed` if both the rotoi` f and the fluid guide are mounted inversely to the 'illustrated construction. l

` What I claim is:

i. A fluid actuable rotor etait, a aan@ @ari-ita by aan u prising a pair of rods radially projecting from said shaft` spaced both longitudinally and circumferentially thereof and a substantially spiral rod connecting the outer ends of said radial rods and a vane formed of sheet material and mounted upon said frame.

2. A fluid actuable rotor comprising a shaft, a pairof rods radially carried by said shaft, and spaced apart both longitudinally l0 and crcumferentially of said shaft, a substantially spiral rod connecting the outer ends of said radial rods, and a vane `formed of sheet material secured at opposite ends to said radial rods, and. attached along its inner edge to said shaft, and attached along its@ outer edge to saidspiral rod.

In testimony whereof I sign this Specification.
